BOTTLE-STOPPER.

Specification of Letters Patent.

Patented Dec. 19, 1905.

T0 all whom t may concern.-

Be it known that we, FRIEDRICH WILHELM VIETMEYER and ALEXANDER VIETMEYER, subjects of the German Emperor, residing at Pyrmont, in the Empire of Germany, have inl vented a new and useful Bottle-Stopper, of which the following is a specification.

Our invention relates to improvements in bottle- Stoppers whereby it is rendered possible to make them essentially of tin-plate and yet capable of withstanding a strong internal pressure in the bottles and remaining tight.

The objects of our improvement are, first, to so draw or otherwise form a convenientlyshaped tin-plate blank as to obtain a cap sufficently stiff to withstand the bottle-pressure without bending and made integral with two or more pendent straight fingers reaching over the neck of the bottle; second, to provide the straight fingers with ribs by the drawing or forming process for the pur ose of strengthening them; third, to sharp y bend the ends of the straight ribbed fingers to form hooks bearing on the shoulder of the bottleneck; fourth, to provide a pad or packingdisk of cork, india-rubber, or other material secured on the inside of the cap, and,fifth,in case the stopper is to be used over and over again to provide the neck of the bottle with two or more faces or recesses for allowing the hooked ends of the stopper-fingers to pass through them, so that the bottle can be closed and opened by turning the stopper through a convenient angle. We attain these objects by the stopper illustrated in the accompanying drawings, in which- Figure 1 shows a blank of tin-plate for a stopper with two fingers. Fig. 2 is a top view of a stopper whose finger ends are not yet bent. Fig. 3 is an elevation of the same. Fig. 4 is a side view of the same. Fig. 5 is a cross-section through the one finger of the stopper on the line y e in Fig. 4. Fig. 6 is a vertical longitudinal section through a bottleneck and the stopper secured thereon, the operation of closing the bottle being indicated by the dotted lines. Fig. 7 is a similar vertical section at right angles to that shown at Fig. 6. Fig. 8 is an elevation of a recessed bottle-neck and the stopper adapted to be used over and over again. Fig. 9 is a top view of the recessed bottle-neck, and Fig. 10 shows a tin-plate blank for a stopper with three lingers.

Similar characters of reference refer to similar parts throughout the several views.-`V

For producing a bottle-stopper with two fingers, as shown at Figs. 2 to 5, inclusive, a blank of tin-plate about of the shape shown at Fig. 1 is used. It is in any known manner so drawn or otherwise formed that a spherically-shaped cap 1 and two straight ribbed fingers 2 2 are obtained. The cap 1 is sufiiciently stiff and strong to resist the internal pressure in the bottle without bending. The straight fingers 2 2 are subjected only to strains and not to any bending moment, and therefore they are strong enough for holding the cap l down on the bottle-neck. By the ribs 3 3 the fingers 2 2 are, moreover, stiffened. .A pad or packing-disk 4, of cork, india-rubber, or other material, is preferably secured on the inside of the cap 1 in any known manner. For instance, the cap 1 is shown as provided with two opposite teeth 5 5, which engage in the pad or packing-disk 4. These teeth 5 5 may be formed by bending the two projections produced by the cuts 6 6 in the blank in Fig. 1.

The stopper described sofar is put over the neck 7 of a bottle and forced thereon in a suitable known machine-for instance, with the aid of a die 8. (Indicated by dotted lines at Fig. 6.) Then by means of two horizontallyguided movable parts 9 9 of the machine the ends of the two ribbed ngers 2 2 are sharply bent around the lower edge of the neck 7. Thus two hooks 11 l 1 are formed, which bear against the shoulder 10 of the neck 7 and -are sufliciently stiffened by the slightly-flattened ribs 12, Fig. 7, to resist the bending moment of the internal pressure of the bottle.

It is of special advantage that the cap 1 by reason of its spherical shape is sufficiently stiff to resist the action of vthe bottle-pressure without bending and that the ribbed fingers 2 2 are not subjected to any bending moment, and therefore not liable to spreading out.

When it is desired toY open the bottle, it is only necessary to.force outwardly either iinger 2 to release it from the shoulder 10 of the neck, after which the stopper can be removed.

lf the stopper is to be used over and over again, the neck 7 of the bottle is preferably providedwith two opposite recesses 13 13, (see Figs. 8 and 9,) which permit the hooks 11 11 to pass through. Then if the latter IOO have been formed in the manner described above, and thereby the bottle closed, it is for opening of the bottle only necessary to turn the stopper through an angle 'of about ninety degrees until the hooks Il 1 1 engage in the recesses 13 13, and the stopper can be removed. It is obvious that for closing the bottle with an accomplished stopper the latter is so put over the neck 7 that the hooks 11 11 pass through the recesses 13 13, and then the stopper is turned through the proper angle. "If necessary, the whole is placed in the machine tofrce the stopper downward, and either the stopper or the bottle alone is turned in a direction, or both may be simultaneously turned in opposite directions, until the hooks 1 1 1 1 engage with the shoulder 1'0 of the neck 7. Oi course the recesses 13 13 maybe replaced by faces.

The stopper may be provided with more than two ingers 2 2. Fig. 10 shows, for eX- ample, a blank from which a stopper with three fingers can be formed by drawing or otherwise.

This stopper can be produced quickly and cheaply and will be found to answer well for bottles containingl liquids rich in carbonio aci The stopper may be varied in its details without deviating from the spirit of our invention. The neck of the bottle was hither to assumed to be conical; but it may also be cylindrical, if so preferred.

What we claim as our invention, and desire to secure by Letters Patent, is-

1, In a stopper for bottles, the combination of a bottle provided with a projecting shoul der or the like, a cork, and a cap consisting of a main body portion seated on and overhanging the cork, said cap having integral pendent arms provided with hooked end portions for engaging the shoulder, ,said arms being longitudinally ribbed from their lower ends toa point adjacent the overhanging body portion of the cap.

2.V In a stopper for bottles,the combination of a bottle provided with a projecting shoulder or the like, acork, a rcap' consisting of a main body portion seated on and overhanging the cork, said cap having integral pendent arms provided on their lower end with hooked portions for engagement with theshoulder, said arms joining the overhanging portion of the cap with a gradual curve providing greater width attheir bases than at the ends of said arms, the said arms being longitudinally ribbed from their lower ends to a point above the bases thereof.

3. In a stopper for bottles,.the combination of a bottle provided with kan annular projecting shoulderrecessed at'two or more points, a cork or the like, a cap comprising a main body portion seated on and adapted to overhang the cork, said overhanging portion being provided with teeth securing the cork to the stopper, said cap also lhaving `integral pendent arms provided With hooked end portions, said arms being tapered towardtheir lower ends and j oiningthe overhanging portion in a gradual curve, said arms being ribbed from their lower ends to a point'adj acent the overhanging portion of thevca 4. In a stopper for bottles,thecomb1nation of a Vbottle provided with aprojecting shoulder recessed at two for more poi-nts, and a cap comprising a main'- body or cork-e engaging portion, said cap having integral pendent arms provided with-hook-shaped ends adapted for enga ement'with said shoulders, said arms being ongitudinally ribbed throughout their length.

' In testimony whereof we have=signed our names tofthis specification inthe presence of two subscribing witnesses.
